Machine Operation; Setup And Adjustments; Changing Blade Speed; Changing Sawblade - Jet HBS-1321VS Operating Instructions Manual

The coolant pump (H) can be
switched on and off independently.
An emergency stop button (F) is
located in the centre of the switch box.
Fig 6
Note:
The saw is equipped with an
automatic Shut-Off.
The saw should stop just after the cut
has been completed. The stop tip has
to be adjusted accordingly.

6. Machine operation

Support long workpieces with helping
roller stands.
Work only with a sharp and flawless
sawblade.
Don't take measurements when the
machine is running
Don't chuck too short in vise.
Use the coolant facility to keep cutting
temperatures down, reduce friction
and extend the life of your sawblade.
Make sure the cutting liquid is properly
contained to the machine.
Use only water soluble cutting
emulsions and dispose of it in an
environmentally friendly manner.
Don't cut magnesium-
high danger to fire.
Semi-Automatic Arm
The saw arm rises automatically after
completion of cut.
You can adjust the height, at which
the arm stops when it raises
automatically on the locking handle
(A, Fig 7)
Fig 7
You can rise and lower the sawarm
with the control buttons (D, G, Fig 6).
Line Laser:
The laser beam allows you to
precisely line up your workpiece.
The laser beam can be switched on
and off as required.
Attention:
Class 2 Laser Product
Do not stare into beam of laser.
Do not point the laser beam at people
or animals.
Do not use the laser beam on highly
reflective materials. Reflected light is
dangerous.

7. Setup and adjustments

General note:
Setup and adjustment work may
only be carried out after the
machine is protected against
accidental starting by pulling the
mains plug.

7.1 Changing blade speed

The general rule is the harder the
material being cut, the slower the
blade speed.
20 m/min
for tool steel, alloy steel and bearing
bronzes.
40 m/min
for mild steel, hard brass or bronze.
60 m/min
for soft brass
6
80 m/min
for aluminium or other light materials.
The machine has a variable cutting
speed range of 20 to 80 m/min
Adjust the knob (A, Fig 8) only while
the machine is running.

7.2 Changing sawblade

Disconnect the machine from the
power source.
The sawblade has to meet the
technical specification.
Check sawblade for flaws (cracks,
broken teeth, bending) before
installation. Do not use faulty
sawblades.
Always wear suitable gloves when
handling sawblades.
Raise the saw arm to the vertical
position and lock in place (close feed
control valve E, Fig 1).
Open the wheel covers.
Move the blade guide assemblies (B,
Fig 9) away from the wheel.
Fig 9
Remove the red blade guard and the
brush assembly.
Release the blade tension and remove
the blade.
Place new blade and make sure the
teeth are pointing the cutting direction
(Fig 10).
